Factual error: Denham is obviously shooting a sound film - he has a sound recordist with him along with the bulky and awkward recording equipment typical for the era, and they discuss the problems of recording dialogue on board. But not once do we see him filming with sound. We see the crew recording dialogue - synchronised sound, recorded on location, which is utterly impossible given the equipment they have and the circumstances under which the fim is being shot. We never see a microphone, a boom pole or a tape recorder. His camera isn't even 'blimped' - soundproofed - and it's handcranked, which makes a racket. They can't be planning on adding the sound later - why have the sound recordist and his bulky and heavy equipment there with them if they are? We see the crew recording dialogue - synchronised sound, recorded on location, which is utterly impossible given the equipment they have and the circumstances under which the fim is being shot. The whole point of post dubbing dialogue is that you don't need a sound recordist in the first place.
Factual error: We are told at some point that Nicole Kidman has dual nationality because she was born in the US. In the final scene, when she is talking with Sean Penn about her future steps, she says she has been deported and given one day to leave the country. She was a US citizen, so it is impossible that she would be "deported".
Factual error: In the scene in the glass elevator, when Mike Teavee wants to push a button, he presses the TV Room button. The elevator stops going down and immediately moves horizontally. The characters within the elevator are thrown against the wall from the sudden change. However, they are thrown against the wall that is in the direction the elevator is now moving, instead of the opposite wall as they should have been. (01:20:15)
Factual error: There is a brief shot of a couple driving through the streets near Eatonville, Florida. In the background a mountain is visible. There are no mountains in Florida.
Factual error: When Yuri is narrating about selling weapons for the US government (this was around the scene when he sells M-16's by the kilo), he mentions Lieutenant Colonel Southern. However, when you see the him, he has Colonel rank, which is a silver eagle. The Lieutenant Colonel rank is a silver leaf, not an eagle.
Factual error: Jodie Foster states that as a propulsion engineer, she knows the internal structure of the plane by heart and has worked extensively on it. The problem with that is that propulsion engineers work on the jet engines - which are all on the outside of the plane, on the wings. Sure, a propulsion engineer might have some basic knowledge of the plane's interior design and engineering, but the in-depth knowledge she claims comes from her job simply isn't right - that's the job of avionics engineers.
Factual error: When the results list is posted at the regional competition. "Wooster, MA" is printed next to Zoey Bloch and Avril Dishaw. The correct spelling of the city is Worcester. Wooster is in Ohio.
Factual error: Shane is a lieutenant and the Principal is Petty Officer first class. Shane states the Principal is the senior officer. This is wrong as the Petty Officer is a Non Commissioned Officer, while Shane is a commissioned officer. Shane outranks the Principal.
Factual error: The crescent as emblem on Saracen pennants is anachronistic as it appeared on Islamic military flags no sooner than the 15th century A.D.
Factual error: At a stop on the Niger River, before they arrived in Mali, Dirk tells Dr. Rojas of "the angel wing clam" and calls them "Petricola Pholadiformis" and says that "this river is the only place on the earth they are found." Three problems: First, Petricola Pholadiformis are actually called "False angel wing" and are found many places in the world in fresh water (but seldom in the Niger River). Second, what's known as the "Angel wing" shell (no "false" in its name) has "Cyrtopleura Costata" as its scientific name. Cyrtopleura Costata ("Angel wing") is found in salt water. Third, Dirk also said they "glow in the dark"; some varieties of Cyrtopleura Costata shells will glow if exposed to ultraviolet light but none glow from their own internal source. Petricola Pholadiformis shells don't glow at all.
Factual error: When Wood's character and the gang go to the match which is supposed to be between West Ham United and Birmingham City the teams we actually see in the football action shots are West Ham United and Gillingham.
Factual error: At the beginning of the movie, the main characters are supposedly in Amsterdam, but everyone is speaking German, it's not just the main characters doing this.
Factual error: When Angela is watching the security video on her laptop of her sister committing suicide, you can see she's playing it using Quicktime. She rewinds a couple of seconds by clicking on the first button of the video player. Actually, when you click this button, it takes you to the beginning of the video. The second button would have rewound it a short time. (00:25:20)
Factual error: In the shot where the laser sights of the assailants come in through the windows and holes in the wall, their angles are far too different from each other. The shooters are standing at a rather great distance from the structure and at more or less the same height. All the laser sights should have more or less the same direction and certainly not make a sweeping motion inside the room. (00:37:30)
